Generalized variational inequalities of the Hartman–Stampacchia–Browder type
No full text We obtain several generalized variational inequalities from an equilibrium theorem due to the first author under more weaker hypothesis and in more general setting than known ones. Our new results extend, unify and improve many known Hartman–Stampacchia–Browder type variational inequalities for u.s.c. or monotone type multimaps. Our proofs are also much simpler than known ones.</p
The desoxazoline asidiacyclamide analogue cyclo(Gly&#8211;Thr&#8211;D-Val&#8211;Thz&#8211;Ile&#8211;Thr&#8211;D-Val&#8211;Thz) acetonitrile monosolvate

The acetonitrile molecule is also located on a twofold axis passing through the C and N atoms. In the peptide, the thiazole rings are faced to each other with a dihedral angle of 9.63&#8197;(15)&#176; and intramolecular N&#8212;H...O and O&#8212;H...O hydrogen bonds are observed. A bifurcated N&#8212;H...(O,O) hydrogen bond links the peptide molecules into a layer parallel to the ab plane
Extensions of Heinz–Kato–Furuta inequality, II
No full text In our preceding note, we discussed a generalized Schwarz inequality, an improvement of the Heinz–Kato–Furuta inequality and an inequality related to the Furuta inequality. In succession, we give further discussions on them from the viewpoint of the covariance–variance inequality and the chaotic order. Finally, we consider a relation between our improvement and Wielandt's theorem.</p

H–d-Phe–d-Pro–Gly methyl ester hydrochloride monohydrate
No full textThe conformation of the title tripeptide methyl ester hydrochloride monohydrate, 1-[2-(methoxycarbonylmethylaminocarbonyl)pyrrolidin-1-ylcarbonyl]-2-phenylethanaminium chloride monohydrate, C17H24N3O4+·Cl−·H2O, is extended, but the structure cannot be classified as any typical secondary structure. Interactions through water molecules and chloride ions were formed, in addition to peptide–peptide hydrogen bonds, stabilizing the molecular packing. In comparison with the previous β-turn structure of the Phe–d-Pro–Gly analogue [Doi, Ichimiya & Asano (2007). Acta Cryst. E63, o4691], it was suggested that the difference between the chiralities of Phe and Pro residues of the title compound is important to induce the β-turn structure
EVALUASI KERUSAKAN LAPIS PERMUKAANPADA RUAS JALAN SURABAYA – TURENKM. 106 400 – KM. 115 150
No full textPembangunan peningkatan jalan Surabaya – Turen Km 106 400 – Km 115 150 dilaksanakan pada tahun 1997 dengan umur rencana 7 tahun, sehingga pada tahun 2004 baru akan dilakukan perbaikan kembali. Tetapi pada ruas jalan Surabaya – Turen tersebut saat ini telah mengalami kerusakan-kerusakan pada perkerasannya. Untuk itu diperlukan evaluasi mengenai penyebab dan akibat dari kerusakan perkerasan jalan tersebut.Dalam hal ini kami mengevaluasi lokasi pada ruas jalan Surabaya – Turen Km 106 400 – Km 115 150
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Qualitative Dosimetric and Radiobiological Evaluation of High – Dose – Rate Interstitial brachytherapy Implants
No full textRadiation quality indices (QI), tumor control probability (TCP), and normal tissue complication probability(NTCP) were evaluated for ideal single and double plane HDR interstitial implants. In the analysis, geometrically–optimized at volume (GOV) treatment plans were generated for different values of inter–source–spacing (ISS) within the catheter, inter–catheter–spacing (ICS), and inter–plane–spacing (IPS) for single - and double - plane implants. The dose volume histograms (DVH) were generated for each plan, and the coverage volumes of 100%, 150%, and 200% were obtained to calculate QIs, TCP, and NTCP. Formulae for biologically effective equivalent uniform dose (BEEUD), for tumor and normal tissues, were derived to calculate TCP and NTCP. Optimal values of QIs, except external volume index (EI), and TCP were obtained at ISS = 1.0 cm, and ICS = 1.0 cm, for single–plane implants, and ISS = 1.0 cm, ICS = 1.0 cm, and IPS = 0.75 to 1.25 cm, for double – plane implants. From this study, it is assessed that ISS = 1.0 cm, ICS = 1.0 cm, for single - plane implant and IPS between 0.75 cm to 1.25 cm provide better dose conformity and uniformity.</p

The neutral chloranilic acid molecule is on an inversion symmetry element and its hydroxy H atoms are disordered over two positions with site-occupancy factors of 0.53&#8197;(6) and 0.47&#8197;(6). The methanol solvent molecule is disordered over two positions in a 0.836&#8197;(4):0.164&#8197;(4) ratio. In the crystal, N&#8212;H...O, O&#8212;H...O and C&#8212;H...O interactions link the components.
